Abstract: One of the main efforts in the process of the digitisation of the battlefield is to build up an integrated information system. The following article describes the approach of the German Army to integrate the Command, Control and Information System, the Battlefield Management System and the developing Command and Fire Control Systems to form an Army Integrated Information System. The Army Integrated Information System is then described as a highly complex integrated system of command and control means comprising information processing means and systems on the one hand and information transmission means and systems on the other. An assessment is then made of the contribution of the integrated system to the individual phases of the command and control process. Within this integrated system, the interchange of information and the impact on the command and control process are discussed and some aspects are indicated for further examination with respect to information management. Attention then focuses on the relationship between the Army Integrated Information System and the Composite Reconnaissance System. Finally, some comments are provided on the further development of the Army Integrated Information System and thus of the Army integrated system of command and control means.
